Sodium carbonate anhydrous is widely used in the manufacturing of glass, where it acts as a flux to lower the melting point of silica, making the production process more energy-efficient. In the detergent industry, it serves as a water softener, helping to remove calcium and magnesium ions from hard water, which enhances the effectiveness of cleaning agents. It is also employed in the paper and pulp industry to adjust pH levels during the pulping process, ensuring optimal conditions for chemical reactions. Additionally, it is used in water treatment to neutralize acidic water and in the textile industry as a pH regulator during dyeing processes. In food processing, it functions as a raising agent and stabilizer, particularly in baked goods. Its versatility extends to the chemical industry, where it is a key ingredient in the production of various sodium compounds.
